Thanks. I did this - but it does not work yet. -- When I'm using web prowser in PC, I can plase "mouse" over menu iten and then it opens sub menus, as it should. This works fine. But when I'm usin mobile, iPhone 6 in this case, Safari, I have no "mouse". When I click top iten in menu, it does not open sub menus but it pics that page immediately linked to that menu item at the top. -- So my concern is how I can open sub menu items without having mouse?

Please ignore that message I posted. ... Now it works, I can see. It really opens sub items when I click that little arrow on top-menu-item. ... I removed all browsing history from Safari's memory in iPhone and then it works ok.
